DAVID S. KENNEDY, OF BROOKLYN, NEW YORK, ASSIGNOB TO MERGENTI-IALER LINOTYPE COMPANY, A CORBORATION OF NEW YORK.

LINE-CASTING MACHINE.

Application filed November 24, 1911.

To all whom it may concern:

Be it known that I, DAVID S. KENNEDY, of the borough of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Line- Casting Machines, of which the following is a specification.

My invention relates to mechanism whereby a single finger key is enabled to actuate alternately two slides or other devices for effecting the delivery of matrices from two channels.

My improvements are intended more particularly for application to the escapement mechanism of Mergenthaler linotype machines of the class shown in United States Letters Patent No. 530,931.

Referring to the drawings Figure 1 is a perspective view representing in outline my mechanism combined with two escapements. Fig. 2 is a side elevation of the same. Fig. 3 is a view of the mechanism adapted to deliver two matrices from each of the channels alternately.

In the drawings, A represents a finger key, mounted midway of its length on the horizontal pivot a.

B, B are two escapement controlling slides or, reeds, each required to be operated alternately by the key.

C and G are two angular pawls pivoted to opposite sides of the key, for the purpose of engaging and lifting the slides, which are notched to receive the upper ends of the pawls. The pawls are each urged upward by a spring a, secured to the side of the key; and were they not otherwise controlled, the pawls would remain in constant engagement with the slides. In order to control the pawls and permit their engagement alternately, I provide two peripherally notched wheels D and D, mounted on the opposite ends of a pivot extending through the key lever. The notches in the wheels are alternated or staggered in such manner that as the wheels are rotated step by step the pawls will be thrown alternately out of engagement. In other words, each pawl will engage one of the slides while the opposite pawl is disengaged from the other slide.

Inorder to eifect the intermitting rotation of the wheels I secure on the pivot with Specification of Letters Patent.

the notched wheels a ratchet wheel E, actuated by a spring pawl F, mounted on a fixed support. A strong spring, G, is eX- tended from the fixed support to the rear of the finger key, and serves to draw the latter downward whenever its forward end is released.

WVhen the finger key is actuated its rear end carries both the pawls upward, one of them, held out of action by the corresponding wheel, remains idle, but the other lifts the slide with which it engages. When the rear end of the finger key is drawn downward the pawl F turns the ratchet wheel. E and the controlling wheels D and D, the latter serving to reverse the position of the pawls and disengage the one which has just lifted a slide, while permitting the other to engage. On the second movement of the lever the slide previously operated remains at rest and the second slide is lifted. In this manner, it will be seen, the two slides are operated alternately.

By suitably changing the peripheral configuration of the wheels D, D, the number of teeth on the wheel E and the eifective position of the pawl F, as will be understood by those skilled in the art, each slide B or B will be caused to be actuated two or more times in succession before the other is actuated. For example, in Fig. 3 the parts are shown as arranged so that the slide B will be actuated twice and will then remain at rest while the slide B is actuated twice, and so on, alternately and repeatedly.

H represents the inclined channeled magazine in which the matrices I, I, are carried, and J, J are pivoted escapements, each carrying at opposite ends two upright pawls which are projected alternately into the magazine by the movement of the lever in the manner practiced in Mergenthaler machines and familiar to those skilled in the art.

The slides B and B may be continued upward to act directly upon the escapements J, J, but I prefer to employ between said parts the mechanism shown in the drawings, consisting of the vertically guided reeds K, K, acting upon the escapements and lifted in turn by the yokes Ii, carrying the cams M, which receive motion from the underlying and continuously rotated rolls N.

The pivoted dogs 0 serve to hold the yokes and cams normally in an elevated inactive position. These dogs are controlled by the slides B and B. These parts are identical with those shown in United States Letters Patent No. 530,931, and form no part of my invention.

The essence of the invention lies in combining with the finger key dogs to actuate two reeds and means for throwing the two dogs into and out of action alternately. It is manifest that the details may be widely nliodified within the range of mechanical s rill.

I prefer to employ the construction represented in Fig. 8, to deliver two or more matrices from one channel before shifting to the other, it being advantageous to have the shifting action occur at long instead of short intervals.

I am aware that it is very old in the art to release several matrices in succession by a finger key mechanism first from one channel of a magazine and then from another channel, the shifting of the connections being effected periodically by mechanism independent of the finger keys as shown in the Mergenthaler Patent 658,740. I am also aware that it is old to efifect the same results by the mechanism shown in Letters Patent of Great Britain No. 19,017 of 1905, the shifting of the connections being effected by power driven mechanism. I am also aware that it is old as shown in United States Letters Patent to Petersen, No. 888,649, and in earlier structures, to release matrices one at a time first from one channel and then from another in alternate order, through shifting mechanism controlled by the key. I believe myself to be the first, however, to construct a mechanism in which a single finger key through intermediate clevices operates two escapements alternately, each escapement releasing two or more matrices in succession before the other escapement is called into action.

While the invention is intended more particularly for application to line casting machines, it will of course be understood that it is also applicable to composing machines, and machines for casting and composing type, type dies, etc.

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Eatents.

Having described my invention, what I claim is:

1. In combination with a pair of matrix channels adapted to contain matrices bearing the same character, cooperating escapement mechanism to release matrices two or more in succession from one of said channels, and then two or more in succession from the other of said channels, a single finger key, and connections actuated and controlled by the repeated actuation of said key to effect the successive operation of the escapement mechanism in the manner indicated.

2. In combination, two escapements, actuating means therefor, a single finger key, and selecting means, controlled ,by the key whereby plural impulses are given to the two escapements alternately.

8. In a typographic machine, the combination of two slides B, B, a single finger key, two pawls carried by said key, and an automatic device for throwing said pawls into engagement with the respective slides alternately.

4. In a typographic machine, the two slides, the finger key, the two pawls connected to the key to engage the slides, the

wheels controlling the operative position of the pawls, the ratchet wheel, and means for rotating the ratchet wheel.

5. The combination of the two slides, the finger key, the two spring-actuated pawls carried by the finger key, the pawl controlling wheels, the ratchet wheel for turning the same, the pawl to actuate the ratchet wheel, and the spring to move the finger J. It. Rooms, EDGAR RoUssnAU.
